While there has been much speculation that Alma Junction is actually The Book of Mormon movie, and very well could be, it should also be noted that Matt Stone and Trey Parker were in the midst of making a deepfake movie utilizing vfx from newly-formed Deep Voodoo studio.
However, one Reddit user has pointed out that in an April 2020 edition of Production Weekly, it revealed that Alma Junction may be a working title for a film adaptation of their hit musical, The Book of Mormon.
The pair’s crowning achievement that isn’t South Park may be the smash Broadway musical The Book of Mormon.
Last year, it was announced that Trey Parker and Matt Stone, the creators of South Park, would be directing their first live-action film together titled Alma Junction.
